The Centers for Disease Control and Prevention, also known as CDC, is a group of people who work together to keep us healthy and safe. They help to prevent the spreading of dangerous diseases, like the flu or Zika virus, and prepare for emergencies like earthquakes, hurricanes or pandemics. They do this by watching and learning about how diseases spread, teaching people how to stay healthy, and helping to create new medicine or treatments that can cure people who are sick. The CDC is like a superhero team that works to save the day and make sure you stay healthy!
